With further advances, it became practical to generate pulses having a width on the same order as the period of the RF carrier (T = 1/f). This is now generally called impulse radar. The first significant application of this technology was in ground-penetrating radar (GPR). Developed in the 1970s, GPR is now used for structural foundation ...
After the Battle of Britain, RAF Bomber Command began night attacks against German cities. Although Bomber Command had reported good results from the raids, the Butt Report showed only one bomb in twenty landed within 5 miles (8.0 km) of the target, half the bombs fell on open country, and in some cases, the bombing was seen to fall as far as 50 kilometres (31 mi) from the target.
Radar coverage along the UK coast, 1939–1940. By 1937, the first three stations were ready, and the associated system was put to the test. The results were encouraging, and the government immediately commissioned construction of 17 additional stations. This became Chain Home, the array of fixed radar towers on the east and south coasts of ...
Later in the war, the Norden was combined with other systems to widen the conditions for successful bombing. Notable among these was the radar system called the H2X (Mickey), which were used directly with the Norden bombsight. The radar proved most accurate in coastal regions, as the water surface and the coastline produced a distinctive radar ...
Alan Dower Blumlein (/ ˈ b l ʊ m l aɪ n /; [1] 29 June 1903 – 7 June 1942) was an English electronics engineer, notable for his many inventions in telecommunications, sound recording, stereophonic sound, television and radar. [2]
The first radar prototypes in Italy were developed as early as 1935 by electronics researcher Ugo Tiberio who, after graduating in 1927 from the Royal School of Engineering in Naples, published some papers on electromagnetism and, during his military service, was posted to the Military Communications Institute in Rome where Colonel Luigi Sacco ...
Based on this, Page, Taylor, and Young are generally credited with developing the world's first radar system. (RADAR is an acronym for RAdio Detection And Ranging. Thus, to be called a "radar," a system must both detect a target and measure the range to the target. Many earlier systems had functioned only to detect without measuring range.)
The RR-144 is designed to prevent interference with civil ATC radar systems. Chaff, originally called Window [1] or Düppel, is a radar countermeasure involving the dispersal of thin strips of aluminium, metallized glass fiber, or plastic. [2] Dispersed chaff produces a large radar cross section intended to blind or disrupt radar systems. [3]
